Any fan of Parks and Recreation knows that the sitcom saw a marked change in tone between its first and second seasons – one that helped Parks become one of TV’s funniest and most heartwarming shows. But how did the series make the shift from halfhearted Office clone to sunny, original comedy? You’ll find out tonight when Entertainment Weekly and Sundance Channel’s new series The Writers’ Room goes inside Parks and Rec. Series star Amy Poehler, co-creator Michael Schur, and the show’s writing team will chat about everything from the sitcom’s origins to what happened when Poehler tried to plant a kiss on Joe Biden to how Leslie Knope found her way – the last of which you’ll see in this clip from the show.

The Writers’ Room airs Mondays at 10 p.m. ET on the Sundance Channel. Parks and Recreation returns on NBC with an hour-long premiere Sept. 26.
